Fellow Time-nuts,
When measuring a pair of OSA 8600 oscillators with a HP5370B I see an
oscillating behaviour. It's a stable variation of about 5,5 s.
I have tried different settings but no luck. I've used the PPS as
start and as External Arming. Very stable pattern.
None of the other counters show the same pattern for the same signal
sources,
Have any other time-nut any good idea what it is?
Cheers,
Magnus
Is it present when one 8600 is measured against itself?
ie use one 8600 to drive both start and stop inputs with PPS derived
from it as the external arm input.
If not present in this case then the effect may be due to a periodic
linearity error in the 5370B.
